How to treat jellyfish sting?

Swimming in hot summer days is great, but we must watch out for jellyfish both in water and on the sand. In case you get stung, remove the tentacles that are clinging to your skin. Don't wash the area with fresh water because it would release more venom into your body. Instead, clean it with rubbing alcohol, ammonia, vinegar or urine. You can also apply meat tenderizer or a mixture of baking soda and water.
